Behavior

A build error occurs:

                 from ../../py/bc.h:30,
                 from ../../shared-module/uheap/__init__.c:9:

Description

No response

Additional information

It's likely that the VERIFY_PTR macro is not correct for split-heap. This has likely been broken for some time as it's not enabled in any builds.
